How does Shopgraph handle payment?
Unauthenticated calls receive a 402 challenge with MPP payment details; authenticated calls with a `payment_method_id` are processed and billed per tool price.

基本信息
AI shopping agents need structured product data to compare prices, check availability, and make decisions. Shopify Catalog covers Shopify merchants. Google UCP covers Google Shopping. ShopGraph covers everything else — the DTC brands, independent retailers, and niche suppliers th

}Extract comprehensive product data from a URL including name, price, brand, images, availability, and more. Uses schema.org structured data when available, with LLM fallback. Costs $0.02 per call (cached results are free). Each field carries verification metadata in _shopgraph: provenance (field_method — which source/tier produced it: schema_org, llm, or hybrid), freshness (field_freshness — recency + volatility_class, for volatile fields like price & availability), and abstain (a field is null when ShopGraph cannot verify it on the page). Rely on provenance, freshness, and the abstain signal to decide what to trust.
Extract basic product attributes from a URL (name, price, brand, availability). Faster and cheaper than enrich_product. 50 free calls/month — no payment needed. Paid: $0.01 per call after free tier. Each field carries verification metadata in _shopgraph: provenance (field_method — which source/tier produced it: schema_org, llm, or hybrid), freshness (field_freshness — recency + volatility_class, for volatile fields like price & availability), and abstain (a field is null when ShopGraph cannot verify it on the page). Rely on provenance, freshness, and the abstain signal to decide what to trust.
Extract product data from raw HTML you already have (no HTTP fetch needed). Ideal when using Bright Data, Firecrawl, or any scraping API — pipe the HTML through ShopGraph for structured product data. Uses schema.org + LLM fallback. Costs $0.02 per call (cached results are free). Each field carries verification metadata in _shopgraph: provenance (field_method — which source/tier produced it: schema_org, llm, or hybrid), freshness (field_freshness — recency + volatility_class, for volatile fields like price & availability), and abstain (a field is null when ShopGraph cannot verify it on the page). Rely on provenance, freshness, and the abstain signal to decide what to trust.
Extract product data and return agent-readiness score (0-100). Scores structured data completeness, semantic richness, UCP compatibility, pricing clarity, and inventory signals. Full scoring breakdown included.
Shopgraph is a Model Context Protocol server that extracts structured product data from URLs using Schema.org data and AI fallback, targeting agents that need product info from the open web where platform APIs are unavailable. It bills per API call via Stripe MPP.
Install with npm install, set STRIPE_TEST_SECRET_KEY and GOOGLE_API_KEY in .env, then build and run via npm start (stdio) or npm run start:http (HTTP). Agents connect via MCP and call enrich_product or enrich_basic with a URL and optional payment_method_id.
enrich_product ($0.02) and enrich_basic ($0.01)Unauthenticated calls receive a 402 challenge with MPP payment details; authenticated calls with a `payment_method_id` are processed and billed per tool price.
Primary extraction from Schema.org markup (0.95 confidence); if none found, Gemini LLM fallback (0.7+ confidence); Playwright browser fallback for bot‑blocked or JS‑rendered pages.
Yes, results returned from cache within the 24‑hour TTL are free of charge.
Node.js, with environment variables `STRIPE_TEST_SECRET_KEY` and `GOOGLE_API_KEY`; optionally, a Playwright browser for the JS‑rendering fallback.
The server can run via stdio (local MCP client) or HTTP (for Vercel/remote deployment). The MCP endpoint is `https://shopgraph.dev/mcp`.

A good sequence diagram can solve almost any communication problem in engineering. Volley lets your agent write them as plain text, with the real request and response payloads on every arrow. It checks its own syntax wi
